What is the ICD-10 code for central sleep apnea?

The ICD-10 code for central sleep apnea is G47.31. This code is used when central sleep apnea is confirmed by polysomnography and is not secondary to another condition.

How is central sleep apnea documented?

Central sleep apnea is documented by confirming central apneas ≥50% of total events on a polysomnography report, with absence of respiratory effort during apneic events.

Code	Description	When to Use	Key Documentation
G47.31	Central sleep apnea	Use when central sleep apnea is confirmed by PSG and is not secondary to another condition.	Polysomnography showing central apneas ≥50% of total events Absence of respiratory effort during apneic events
G47.32	Central sleep apnea in high altitude periodic breathing	Use when central sleep apnea is due to high altitude periodic breathing.	Patient recently ascended to ≥2 500 meters PSG shows periodic breathing pattern
G47.37	Central sleep apnea in conditions classified elsewhere	Use when central sleep apnea is secondary to another condition.	Documentation states 'Central apneas secondary to [condition]' Cheyne-Stokes respiration due to heart failure

Documentation & Coding Risks

Avoid these common issues when documenting Central Sleep Apnea.

Documenting 'sleep apnea' without specifying type

Impact

Clinical: Leads to inappropriate treatment plans., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials due to lack of specificity.

Mitigation

Always specify the type of sleep apnea in documentation., Ensure PSG results are reviewed and documented.

Coding G47.31 for CSA with Cheyne-Stokes

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation

Use G47.37 + R06.3 for CSA with Cheyne-Stokes respiration.

PSG documentation

Impact

Lack of PSG documentation for CSA claims.

Mitigation

Ensure PSG reports are included in patient records.
